Definitions

As used herein the following definitions apply unless clearly indicated otherwise.

All atoms designated within a Formula described herein, either within a structure provided, or within the definitions of variables related to the structure, is intended to include any isotope thereof, unless clearly indicated to the contrary. It is understood that for any given atom, the isotopes may be present essentially in ratios according to their natural occurrence, or one or more particular atoms may be enhanced with respect to one or more isotopes using synthetic methods known to one skilled in the art. Thus, hydrogen includes for example ¹H, ²H, ³H; carbon includes for example ¹¹C, ¹²C, ¹³C, ¹⁴C; oxygen includes for example ¹⁶O, ¹⁷O, ¹⁸O; nitrogen includes for example ¹³N, ¹⁴N, ¹⁵N; sulfur includes for example ³²S, ³³S, ³⁴S, ³⁵S, ³⁶S, ³⁷S, ³⁸S; fluoro includes for example ¹⁷F, ¹⁸F, ¹⁹F; chloro includes for example ³⁵Cl, ³⁶Cl, ³⁷Cl, ³⁸Cl, ³⁹Cl; and the like.

Certain compounds contemplated for use in accordance with the present disclosure can exist in unsolvated forms as well as solvated forms, including hydrated forms. “Hydrate” refers to a complex formed by combination of water molecules with molecules or ions of the solute. “Solvate” refers to a complex formed by combination of solvent molecules with molecules or ions of the solute. The solvent can be an organic compound, an inorganic compound, or a mixture of both. Solvate is meant to include hydrate, hemi-hydrate, channel hydrate etc. Some examples of solvents include, but are not limited to, methanol, N,N-dimethylformamide, tetrahydrofuran, dimethylsulfoxide, and water.

US 2007/0032519, US 2009/0076046 and US 2011/0112127. Compound I and II have IC₅₀ values of less than 0.05 μM for each of these three kinase targets.

As used herein, the term “Fms and/or Kit and/or Flt3 protein kinase mediated disease or condition” refers to a disease or condition in which the biological function of a Fms protein kinase, including any mutation thereof, a Kit protein kinase, including any mutation thereof, a Flt3 protein kinase, including any mutation thereof or both a Fms and Kit protein kinase, including any mutations thereof, affects the development, course, and/or symptoms of the disease or condition, and/or in which modulation of the Fms and/or Kit and/r Flt3 protein kinase alters the development, course, and/or symptoms of the disease or condition. A Fms and/or Kit and/or Flt3 protein kinase mediated disease or condition includes a disease or condition for which modulation provides a therapeutic benefit, e.g. wherein treatment with Fms and/or Kit and/or Flt3 protein kinase inhibitor(s), including one or more solid, crystalline or polymorphs of Compound I or solid or crystalline forms of Compound II as described herein, or a composition thereof as described herein, and optionally in combination with another therapeutic agent or therapy as described herein provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition.

As used herein, the terms “Fms protein kinase mediated disease or condition,” “c-Fms mediated disease or condition,” and the like refer to a disease or condition in which the biological function of a Fms protein kinase, including any mutations thereof, affects the development, course, and/or symptoms of the disease or condition, and/or in which modulation of the Fms protein kinase alters the development, course, and/or symptoms of the disease or condition. The Fms protein kinase mediated disease or condition includes a disease or condition for which Fms inhibition provides a therapeutic benefit, e.g. wherein treatment with Fms inhibitor(s), including one or more solid, crystalline or polymorphs of Compound I or solid or crystalline forms of Compound II as described herein, or a composition thereof as described herein, and optionally in combination with another therapeutic agent or therapy as described herein provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition.

As used herein, the terms “Kit protein kinase mediated disease or condition,” “c-Kit mediated disease or condition,” and the like refer to a disease or condition in which the biological function of a Kit protein kinase, including any mutations thereof, affects the development, course, and/or symptoms of the disease or condition, and/or in which modulation of the Kit protein kinase alters the development, course, and/or symptoms of the disease or condition. The Kit protein kinase mediated disease or condition includes a disease or condition for which Kit inhibition provides a therapeutic benefit, e.g. wherein treatment with Kit inhibitor(s), including one or more solid, crystalline or polymorphs of Compound I or solid or crystalline forms of Compound II as described herein, or a composition thereof as described herein, and optionally in combination with another therapeutic agent or therapy as described herein provides a therapeutic benefit to the subject suffering from or at risk of the disease or condition.

As used herein, the term “composition” refers to a pharmaceutical preparation suitable for administration to an intended subject for therapeutic purposes that contains at least one pharmaceutically active compound, including any solid form thereof. The composition may include at least one pharmaceutically acceptable component to provide an improved formulation of the compound, such as a suitable carrier or excipient.

As used herein, the term “subject” refers to a living organism that is treated with compounds as described herein, including, but not limited to, any mammal, such as a human, other primates, sports animals, animals of commercial interest such as cattle, farm animals such as horses, or pets such as dogs and cats.

The term “pharmaceutically acceptable” indicates that the indicated material does not have properties that would cause a reasonably prudent medical practitioner to avoid administration of the material to a patient, taking into consideration the disease or conditions to be treated and the respective route of administration. For example, it is commonly required that such a material be essentially sterile, e.g., for injectibles.

In the present context, the term “therapeutically effective” or “effective amount” indicates that the materials or amount of material is effective to prevent, alleviate, or ameliorate one or more symptoms of a disease or medical condition, and/or to prolong the survival of the subject being treated. The therapeutically effective amount will vary depending on the compound, the disorder or condition and its severity and the age, weight, etc., of the mammal to be treated. For example, an effective amount is an amount sufficient to effectuate a beneficial or desired clinical result. The effective amounts can be provided all at once in a single administration or in fractional amounts that provide the effective amount in several administrations. The precise determination of what would be considered an effective amount may be based on factors individual to each subject, including their size, age, injury, and/or disease or injury being treated, and amount of time since the injury occurred or the disease began. One skilled in the art will be able to determine the effective amount for a given subject based on these considerations which are routine in the art.

As used herein, the term “modulating” or “modulate” refers to an effect of altering a biological activity, especially a biological activity associated with a particular biomolecule such as a protein kinase. For example, an inhibitor of a particular biomolecule modulates the activity of that biomolecule, e.g., an enzyme, by decreasing the activity of the biomolecule, such as an enzyme. Such activity is typically indicated in terms of an inhibitory concentration (IC₅₀) of the compound for an inhibitor with respect to, for example, an enzyme.

As used herein, the phrase “substantially as shown in Figure” as applied to DSC thermograms is meant to include a variation of ±3° Celsius and as applied to thermogravimetric analysis (TGA) is meant to include a variation of ±2% in weight loss.

As used herein, the phrase “major peaks” in the XRPD pattern refers to a subset of the entire observed peak list. Major peaks are selected from observed peaks by identifying preferably non-overlapping, low-angle peaks, with strong intensity.

In the context of the use, testing, or screening of compounds that are or may be modulators, the term “contacting” means that the compound(s) are caused to be in sufficient proximity to a particular molecule, complex, cell, tissue, organism, or other specified material that potential binding interactions and/or chemical reaction between the compound and other specified material can occur.

In addition, abbreviations as used herein have respective meanings as follows:

Compounds I and II

Compounds I and II were synthesized according to the following synthetic procedure of Scheme I:

Step 1: Conversion of (a) to (c)

The reactor was charged with isopropyl alcohol, and the chamber was flushed with nitrogen. Tert-butyl[(tert-butoxy)-N-(5-formyl-(2-pyridyl))carbonylamino]formate (a) was dissolved in isopropyl alcohol with stirring, and the reaction mixture was cooled to about 0-5° C. 5-Chloro-7-azaindole (b), potassium carbonate, and tetrabutylammonium bisulfate were added one by one to the reactor, and the reaction mixture was stirred at room temperature for about 24 hours. The reaction progress was monitored by analyzing the reaction mixture by HPLC. When the content of (a) was 2% or less, the reaction was cooled to about 5-10° C., and purified water was added to precipitate crude tert-butyl[(tert-butoxy)-N-{5-[(5-chloropyrrolo[2,3-b]pyridine-3-yl)hydroxymethyl]-(2-pyridyl)}carbonylamino)formate (c). The precipitate was filtered, washed with purified water, dried, and tested for purity. If the purity was >90% no further work-up was conducted. If the purity was <90%, the crude product was stirred with hot ethyl acetate for about 1 hour, cooled to about 0-5° C., and filtered. The filtered solids were washed with ethyl acetate and dried.

Step 2: Conversion of (c) to (d)

The reactor was charged with acetonitrile, and the chamber was flushed with nitrogen. Compound (c) was dissolved in acetonitrile with stirring, and the reaction mixture was cooled to about 0-5° C. Triethylsilane and trifluoroacetic acid were added to the reactor, and the reaction mixture was stirred at room temperature for about 24 hours and then refluxed for about 8 hours. The reaction progress was monitored by analyzing the reaction mixture by HPLC. When the (c) content was ≤1.0%, crude 5-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-ylmethyl]-pyridin-2-ylamine trifluoroacetic acid salt (d) was precipitated by concentrating the volume, adding water, and concentrating again. The suspension was stirred for 1 to 1.5 hours at about 60-65° C., cooled to about 0-5° C., and filtered, and the resulting solids were washed with purified water. The solids were then stirred with ethyl acetate for about 3 hours, filtered, washed with ethyl acetate and dried.

Step 3: Conversion of (d) to Compound II (Free Base)

The reactor was charged with acetonitrile, and the chamber was flushed with nitrogen. Compound (d) and 6-trifluoromethyl-pyridine-3-carboxaldehyde (e) were dissolved in acetonitrile with stirring, and the reaction mixture was cooled to about 0-5° C. Trifluoroacetic acid was added to the reactor, and the reaction mixture was stirred for about 6 hours at about 10° C. Triethylsilane was then added to the reactor, and the reaction mixture was refluxed for about 24 hours. The reaction progress was monitored by analyzing the reaction mixture by HPLC. When Compound II content was <1.0% the reaction was worked up by concentrating the volume, adding water, and concentrating again. Ammonium hydroxide was then added to raise the pH of the liquid to be between 8 and 9 and precipitate crude Compound II. The solids were filtered, washed with purified water and dried.

Step 4: Conversion of Compound II to Compound I.

The reactor was charged with ethyl acetate, and the chamber was flushed with nitrogen. Compound II was heated with ethyl acetate at about 55° C. for 7 to 8 hours, cooled to room temperature, stirred for about 16 hours, filtered, and dried. Compound II was reacted with 1.25 equivalents of hydrochloric acid in methanol at <30° C. then heated at reflux for about 1 hour, filtered then cooled to room temperature. The slurry was filtered and the solids were refluxed in methyl tert-butyl ether, cooled to room temperature, filtered, and dried to isolate Compound I.

Characterization of Crystalline Forms A-D of Compound I and Crystalline Compound II

Compound I Form A

Form A is unsolvated. Form A was obtained as described in Example 1 and was utilized as the source material for the polymorph screen. Form A was also obtained from the desolvation of Form D, which is a methanol solvate, under mild heating conditions.

The approximate solubility of Form A was calculated in a variety of solvents using the Solvent Addition Method discussed in the Examples and the results are as shown below.

Approximate Solubility of Compound I Form A.

Solubility Solvent (mg/mL)¹ Acetone <2 Acetonitrile (ACN) <2 Dichloromethane (DCM) <2 1,4-Dioxane <2 Dimethyl Formamide (DMF) >145 Dimethyl Sulfoxide (DMSO) >153 Ethanol (EtOH) 5 Ethyl Acetate (EtOAc) <2 Heptane <2 Isopropyl alcohol (IPA) 2 Methanol (MeOH) 31 Methyl tert-Butyl Ether (MTBE) <2 Tetrahydrofuran (THF) <2 Toluene <2 Water <2 ¹Solubilities are calculated based on the total solvent used to give a solution; actual solubilities may be greater because of the volume of the solvent portions utilized or a slow rate of dissolution. Solubilities are rounded to the nearest mg/mL.

The thermograms of the Form A are displayed in FIG. 2 and FIG. 3. The DSC curve exhibits a melt and concurrent decomposition endotherm with an onset temperature at 222° C. (signal maximum at 231° C.). A minor endotherm is also observed at about 76° C. This event is likely related to a phase transition based on physical stability and hotstage microscopy data. The TG curve exhibits a negligible weight loss up to 150° C., suggesting that it is not solvated. Weight loss above this temperature is due to decomposition.

These thermal events were investigated by hotstage microscopy. The material exhibits birefringence and extinction, typical for crystalline material. A change in birefringence was observed near 65° C. (consistent with the minor endotherm in the DSC above) followed by two distinct melt onsets (184 and 196° C.). These events suggest that a partial phase transformation occurred upon heating, resulting in a mixture of two forms, each with a distinct melt.

The physical stability of Form A was investigated in order to support the hotstage microscopy observations and the results are shown in the table below.

Conditions Description XRPD Result 80° C./7d (<<100 mg) White solid C 80° C./4d (<100 mg) Off-white solid A 80° C./4d (8d consecutive, <100 mg) Off-white solid A RT/85% RH/14d White solid A + minor C 40° C./75% RH/14d White solid A + C

A small sample of Form A (<<100 mg) converted to Form C (unsolvated form) upon exposure to 80° C. for 7 days. A partial conversion to Form C was obtained when Form A was exposed to elevated humidity. In addition, complete conversion to Form C was obtained when Form A was slurried in ethanol for 21 days. This indicates that Form A is physically metastable (at the conditions investigated) and will undergo a phase transition to Form C.

The DVS isotherm suggests that Form A is hygroscopic (FIG. 4). During the sorption step, the material exhibits a weight gain of 0.6% from 5% to 75% RH and an additional 1.7% weight above 75% RH. Minor hysteresis was observed upon desorption. The resulting sample was Form A, by XRPD.

The ¹H NMR spectrum is consistent with the structure of Compound I (FIG. 14, top one). Peaks at approximately 2.5 and 3.6 ppm are assigned to deuterated DMSO (due to residual protons in the NMR solvent) and water, respectively.

Raman and IR spectra (FIG. 5 and FIG. 15, respectively) of Form A were obtained for comparison with that of Form B. The spectra for each exhibit a flat baseline with generally well resolved and sharp bands. Differences within the Raman spectra between the forms were negligible. However, there are differences in intensities and band positions between the IR spectra, indicating that there are chemical and/or physical differences between the forms. Several obvious IR differences in intensities and band positions were noted at approximately 3500-2600 cm⁻¹, 1645 cm⁻¹, and 1110 cm⁻¹.

Thus, Form A is unsolvated. It is hygroscopic above 75% RH. Form A is physically metastable (at the conditions investigated) and can convert to Form C.

Compound I Form B

Form B was obtained as described in Example 2 and was utilized for an analytical comparison with other forms.

The XRPD of Form B contains all the X-ray reflections observed in the pattern of Form C, as well as additional reflections. A comparison of both patterns is shown in FIG. 18. This suggests that Form B is a two phase mixture comprised of Form C (unsolvated form) and a hydrated form based on the characterization described below.

The thermograms of Form B are displayed in FIG. 7 and FIG. 8. The DSC curve exhibits a broad desolvation endotherm (with shoulder) with a signal maximum at 127° C. This event is associated with a TG weight loss of approximately 6.0% (up to 150° C.). Assuming this is due to the volatilization of water (no other solvents were identified by NMR), the weight loss corresponds to 1.5 moles of water for every mole of Compound I. Karl Fischer analysis indicates the material contains 3.45% water by weight. (The water content discrepancy between techniques may be due to losses upon ambient storage. While this explanation has not been confirmed, the KF analysis was performed 14 days after the TG analysis.) In the DSC curve, a minor exotherm and endotherm are also observed at 187 and 203° C., respectively. These events are likely related to a phase transition, based on physical stability and hotstage microscopy data (see below). A sharp endotherm with an onset temperature of 226° C. (signal maximum at 233° C.) is due to the melt and concurrent decomposition. Significant decomposition weight losses are observed at this temperature by TG.

These thermal events were investigated by hotstage microscopy. The material exhibits birefringence and extinction. A loss of birefringence and a solid to liquid transition was observed between about 70 and about 130° C., consistent with the desolvation event described by the TG and DSC thermograms above. Recrystallization was observed near 142° C. and was followed by a melt between about 192° C. and about 200° C.

The physical stability of Form B was investigated in order to support the hotstage microscopy observations. Desolvation/conversion to Form C (unsolvated form) was obtained by exposing Form B to about 150° C. for about 5 minutes.

The ¹H NMR spectrum is consistent with the structure of Compound I (FIG. 14, middle one). Minor peaks at approximately 7.1, 7.25, and 7.38 ppm were not identified. Peaks at approximately 2.5 and 4.1 ppm are assigned to deuterated DMSO (due to residual protons in the NMR solvent) and water, respectively.

Raman and IR spectra (FIG. 9 and FIG. 16, respectively) of Form B were obtained for comparison with that of Form A (unsolvated). The spectra for each exhibit a flat baseline with generally well resolved and sharp bands. Differences within the Raman spectra between the forms were negligible. However, there are differences in intensities and band positions between the IR spectra, indicating that there are chemical and/or physical differences between the forms. Several obvious IR differences in intensities and band positions were noted at approximately 3500-2600 cm⁻¹, 1645 cm⁻¹, and 1110 cm⁻¹.

Thus, based on XRPD, Form B is a two phase mixture comprised of Form C and an unidentified hydrated form. Desolvation/conversion of Form B to Form C was obtained by exposing the material to about 150° C. for about 5 minutes.

Compound I Form C

Form C is unsolvated. Form C was obtained from a wide variety of experiments as discussed in Example 3 and, consequently, was the most frequently observed form. It was crystallized directly out of ethanol by a crash cool experiment, obtained from thermal conversion of Form A, and through the desolvation of Form B or Form D.

The thermograms of Form C are displayed in FIG. 11 and FIG. 12. The DSC curve exhibits a sharp endotherm, indicative of a melt, with an onset temperature at about 227° C. (signal maximum at 234° C.). The TG curve exhibits a negligible weight loss up to the melt endotherm, suggesting that the material is not solvated. Significant weight loss at and above this temperature indicate that decomposition occurs concurrently with the melt.

The DVS isotherm suggests that Form C is less hygroscopic than Form A (FIG. 13). During the sorption step, the material exhibits a weight gain of only 0.96% from 5% to 95% RH. Minor hysteresis was observed upon desorption. The resulting sample remained unchanged by XRPD.

Form C is more physically stable than Form A. As discussed above, Form C was obtained through the conversion of Form A by exposure to elevated temperature or humidity. In addition, a complete conversion to Form C was obtained when Form A was slurried in ethanol for 21 days (Example 3). This indicates that Form A is physically metastable and will undergo a solid state phase transition to Form C.

The ¹H NMR spectrum is consistent with the structure of Compound I (FIG. 14, bottom one). Peaks at approximately 2.5 and 3.6 ppm are assigned to deuterated DMSO (due to residual protons in the NMR solvent) and water, respectively.

Thus, Form C is an unsolvated form that melts concurrently with decomposition at about 227° C. It is less hygroscopic than Form A. Form C is the physically stable unsolvated form.

Compound I Form D

Form D appears to be a methanol solvate. It was crystallized directly out of (88:12) acetone/MeOH by a slow cool experiment (Example 3). It was also obtained by exposing Form A to methanol vapor.

The DSC scan of Form D displays a broad endotherm with a peak maximum at approximately 70° C. that suggests loss of volatile components. Form D also exhibited approximately 5.3% weight loss upon equilibration at 5% RH, confirming that the material contained at least that amount of volatile easily removed at low RH conditions. During the sorption/desorption phases of the experiment, the sample exhibited negligible weight gain (0.9%)/loss (0.9%), similar to the isotherm observed for Form C. The TG curve exhibits about 6% weight loss up to 73° C.

The physical stability of Form D was investigated. The form desolvated to Form A upon exposure to 80° C. for 15 minutes. The material then converted to Form C upon continued exposure to 80° C. for 2 days.

Thus, based on the method of preparation and previous characterization data, Form D appears to be a methanol solvate. The form desolvates to Forms A or C upon exposure to elevated temperatures.

Compound I Amorphous

Compound I amorphous was isolated through rotary evaporation from trifluoroethanol. It was obtained by dissolving 20 mg of Compound I Form A in 100 μL of trifluoroethanol and rotary evaporation at 60° C. for 7 minutes provided the amorphous form as a white solid. The XRPD indicates amorphous material (FIG. 19).

Compound II

Compound II was prepared by the synthetic method above and the resulting crystals were characterized.

The DSC thermogram of free base is displayed in FIG. 21. The DSC curve displays a small endotherm at approximately 124° C. with a larger endotherm at approximately 192° C. that is consistent with sample melting.

DVS results indicate 0.3-0.4% weight loss upon equilibration at 5% RH (FIG. 22). Results for the freebase show that the majority of the weight gained (˜21.6%) is from 45% to 95% RH. The sample subsequently loses all weight gained during the desorption phase. The free base appears to be hygroscopic.

Light microscopy observations were made. The free base exhibits birefringence with extinction when the microscope stage is rotated. Additionally, it exhibits flow when pressure is applied to the cover glass, suggesting that the material is a mesophase or a condis crystal. Images of the free base show bladed-micaceous particles.

The histone deacetylase inhibitors (HDAC inhibitors) are cytostatic agents that inhibit the proliferation of tumor cells in culture and in vivo by inducing cell cycle arrest, differentiation and/or apoptosis. HDAC inhibitors exert their anti-tumor effects via the induction of expression changes of oncogenes or tumour suppressor, through modulating that the acetylation/deactylation of histones and/or non-histone proteins such as transcription factors. Histone acetylation and deacetylation play important roles in the modulation of chromatin topology and the regulation of gene transcription. Non-limiting examples of HDAC inhibitors include vorinostat, romidepsin, chidamide, panobinostat, belinostat, valproic acid, mocetinostat, abexinostat, entinostat, resminostat, givinostat, and quisinostat. HDAC inhibitors have been used extensively in psychiatry and neurology as mood stabilzers and anti-epileptics. One example of this is valproic acid, marketed as a drug under the trade names Depakene, Depakote, and Divalproex. HDAC inhibitors are also being used as a mitigator for neurodegenerative diseases such as Alzheimer's disease and Huntington's disease.

Kinase Activity Assays

A number of different assays for kinase activity can be utilized for assaying for active modulators and/or determining specificity of a modulator for a particular kinase or group of kinases, such as those described in U.S. Pat. Pub. No. 2014/0037617, which is hereby incorporated by reference in its entirety. One of ordinary skill in the art can readily identify other assays that can be utilized and can modify an assay for a particular application. For example, numerous papers concerning kinases describe assays that can be used.

Additional alternative assays can employ binding determinations. For example, this sort of assay can be formatted either in a fluorescence resonance energy transfer (FRET) format, or using an AlphaScreen (amplified/uminescentproximity homogeneous assay) format by varying the donor and acceptor reagents that are attached to streptavidin or the phosphor-specific antibody.

EXAMPLES A. Experimental Methods Approximate Solubility—Solvent Addition Method

A weighed sample was treated with aliquots of the test solvent at room temperature. The mixture was sonicated between additions to facilitate dissolution. Complete dissolution of the test material was determined by visual inspection. Solubility was estimated based on the total solvent used to provide complete dissolution. The actual solubility may be greater than the value calculated because of the use of solvent aliquots that were too large or due to a slow rate of dissolution. If complete dissolution was achieved as a result of only one aliquot addition, the solubility is expressed as “greater than.”

Crystallization Screen

Both thermodynamic and kinetic crystallization techniques were employed. These techniques are described in more detail below. Once solid samples were harvested from crystallization attempts, they were either examined under a microscope for birefringence and morphology or observed with the naked eye. Solid samples were then analyzed by XRPD, and the crystalline patterns compared to each other to identify new crystalline forms.

Ambient Solution (AS)

Solutions were prepared in various solvents at ambient temperature. The solution was filtered through a 0.2-μm filter. An antisolvent was added until turbidity was achieved or until a maximum volume was obtained. Solutions were capped and then allowed to sit at ambient.

Crash Cool (CC)

Saturated solutions were prepared in various solvents at elevated temperature. The solutions were filtered through a pre-warmed 0.2-μm filter and then placed directly into a freezer.

Fast Evaporation (FE)

Solutions were prepared in various solvents and sonicated between aliquot additions to assist in dissolution. Once a mixture reached complete dissolution, as judged by visual observation, the solution was filtered through a 0.2-μm filter. The filtered solution was allowed to evaporate at ambient in an uncapped vial.

Grinding (Mixer Mill)

A solid sample was placed into a ceramic grinding jar with a grinding ball. A small amount of solvent may have also been added. The sample was then ground at 30 Hz on a Retesh type MM220 mixer mill for 20 minutes. The solids were isolated and analyzed.

Rotary Evaporation (RE)

Solutions prepared in various solvents were placed on the rotary evaporator and removed when dry. Some samples were further dried in a vacuum oven at elevated temperature.

Slow Cool (SC)

Saturated solutions were prepared in various solvents at elevated temperatures and filtered through a 0.2-μm filter into a vial while still warm. The vial was sealed and allowed to cool slowly to room temperature (some samples started directly from ambient temperature). The presence or absence of solids was noted. If there were no solids present, or if the amount of solids was judged too small for XRPD analysis, the vial was placed in a refrigerator. Again, the presence or absence of solids was noted and if there were none, the vial was placed in a freezer. Solids that formed were isolated by filtration and allowed to dry prior to analysis.

Slow Evaporation (SE)

Solutions were prepared in various solvents and sonicated between aliquot additions to assist in dissolution. Once a mixture reached complete dissolution, as judged by visual observation, the solution was filtered through a 0.2 μm filter. The solution was allowed to evaporate at ambient in a vial covered with aluminum foil perforated with pinholes unless otherwise noted.

Slurry Experiments

Solutions were prepared by adding enough solids to a given solvent so that excess solids were present. The mixture was then agitated in a sealed vial at either ambient or a set temperature.

Solid Vapor Stress (VS)

A solid sample was placed into a small glass vial, and then placed into a large capped vial containing solvent. The vials were left vertically and undisturbed at ambient.

Stress Experiments

Solids were stressed under different temperature and/or relative humidity (RH) environments for a measured time period. Specific RH values were achieved by placing the sample inside sealed chambers containing saturated salt solutions. The salt solutions were selected and prepared following an ASTM standard procedure.

B. Instrumental Techniques Differential Scanning Calorimetry (DSC)

The data acquisition parameters are displayed on each thermogram in the Data section of this report. Each sample was placed into an aluminum DSC pan, and the weight accurately recorded. Indium metal was used as the calibration standard.

Dynamic Vapor Sorption/Desorption (DVS)

Moisture sorption/desorption data were collected on a VTI SGA-100 Vapor Sorption Analyzer under a nitrogen purge. Equilibrium criteria and the relative humidity (RH) range used for analysis are displayed on each spreadsheet record in the Data section of this report. Data were not corrected for the initial moisture content of the samples. Sodium chloride and polyvinylpyrrolidine were used as calibration standards.

Hot Stage Microscopy

Hot stage microscopy was performed using a Linkam hot stage (model FTIR 600) mounted on a Leica DM LP microscope equipped with a SPOT Insight™ color digital camera. Temperature calibrations were performed using USP melting point standards. Samples were placed on a cover glass, and a second cover glass was placed on top of the sample. As the stage was heated, each sample was visually observed using a 20× objective with crossed polarizers and a first order red compensator. Images were captured using SPOT software (v. 4.5.9).

Coulometric Karl-Fischer Analysis (KF)

Coulometric Karl Fischer (KF) analysis for water determination was performed using a Mettler Toledo DL39 Karl Fischer titrator. The sample was placed in the KF titration vessel containing of Hydranal—Coulomat AD and mixed for 60 seconds to ensure dissolution. The sample was then titrated by means of a generator electrode which produces iodine by electrochemical oxidation: 2 I−=>I₂+2e. The sample size was optimized by performing a scoping experiment. Two replicates were obtained to ensure reproducibility. The value reported is the average of the two replicates.

Infrared Spectroscopy (IR)

IR spectra were acquired on a Magna-IR 860® Fourier transform infrared (FT-IR) spectrophotometer (Thermo Nicolet) equipped with an Ever-Glo mid/far IR source, an extended range potassium bromide (KBr) beamsplitter, and a deuterated triglycine sulfate (DTGS) detector. An attenuated total reflectance (ATR) accessory (Thunderdome™, Thermo Spectra-Tech), with a germanium (Ge) crystal was used for data acquisition. The data acquisition parameters for each spectrum are displayed above the image in the Data section of this report. A background data set was acquired with a clean Ge crystal. A Log 1IR (R=reflectance) spectrum was acquired by taking a ratio of these two data sets against each other. Wavelength verification was performed using NIST SRM 1921b (polystyrene).

Nuclear Magnetic Resonance (NMR)

The solution phase ¹H NMR spectra were collected at Spectra Data Services, Inc. The spectra acquisition parameters are printed on each spectrum in the Data section of this report. Spectra were referenced to internal tetramethylsilane at 0.0 ppm.

Raman Spectroscopy

Raman spectra were acquired on a Raman accessory module interfaced to a Magna-IR 860® Fourier transform infrared (FT-IR) spectrophotometer (Thermo Nicolet) equipped with an indium gallium arsenide (InGaAs) detector. Wavelength verification was performed using sulfur and cyclohexane. Each sample was prepared for analysis by pressing into a pellet and placing it into a pellet holder. The data acquisition parameters for each spectrum are displayed above the image in the Data section of this report.

Thermogravimetry (TG)

The data acquisition parameters are displayed on each thermogram in the Data section of this report. The sample was placed in an aluminum sample pan and inserted into the TG furnace. Nickel and Alumel™ were used as the calibration standards.

X-Ray Powder Diffraction (XRPD)

XRPD patterns of some forms of Compound I were collected with a PANalytical X'Pert PRO MPD diffractometer using the following experimental setting: 45 kV, 40 mA, Kal=1.5406 Å, scan range 1.01-39.98° 2θ, step size 0.017° 2θ, collection time: 1936 s. XRPD patterns of some other forms of Compound I were collected with a Intel XRG-3000 Diffractometer using the following experimental setting: 40 kV, 30 mA, step size 0.03° 2θ, collection time: 300 s.

XRPD data shown in FIGS. 1, 6 and 10 was collected using PANalytical X'Pert Pro Diffractometer and the XRPD data shown in FIG. 17 was collected using Intel XRG-3000 Diffractometer.

The data presented contain X-ray diffraction patterns with tables with peak lists. The range of data collected is instrument dependent. Under most circumstances, peaks within the range of up to about 30° 20 were selected. Rounding algorithms were used to round each peak to the nearest 0.1° or 0.01° 2θ, depending upon the instrument used to collect the data and/or the inherent peak resolution. The location of the peaks along the x-axis (° 2θ) in both the figures and the tables were determined using proprietary software (TRIADS, version 2) and rounded to one or two significant figures after the decimal point based upon the above criteria. Peak position variabilities are given to within ±0.2° 2θ based upon recommendations outlined in the USP discussion of variability in X-ray powder diffraction (United States Pharmacopeia, USP 37, NF 32, through S2<941>, 503, Dec. 1, 2014). The accuracy and precision associated with any particular measurement reported herein has not been determined. Moreover, third party measurements on independently prepared samples on different instruments may lead to variability which is greater than ±0.2° 2θ. For d-space listings, the wavelength used to calculate d-spacings was 1.5405929 Å, the Cu-K_(α1) wavelength (Phys. Rev. A56(6) 4554-4568 (1997). Variability associated with d-spacing estimates was calculated from the USP recommendation, at each d-spacing, and provided in the respective data tables.

Per USP guidelines, variable hydrates and solvates may display peak variances greater than 0.2° 2θ and therefore peak variances of 0.2° 2θ are not applicable to these materials.

If multiple diffraction patterns are available, then assessments of particle statistics (PS) and/or preferred orientation (PO) are possible. Reproducibility among XRPD patterns from multiple samples analyzed on a single diffractometer indicates that the particle statistics are adequate. Consistency of relative intensity among XRPD patterns from multiple diffractometers indicates good orientation statistics. Alternatively, the observed XRPD pattern may be compared with a calculated XRPD pattern based upon a single crystal structure, if available. Two-dimensional scattering patterns using area detectors can also be used to evaluate PS/PO. If the effects of both PS and PO are determined to be negligible, then the XRPD pattern is representative of the powder average intensity for the sample and prominent peaks may be identified as “Representative Peaks”. In general, the more data collected to determine Representative Peaks, the more confident one can be of the classification of those peaks.

“Characteristic peaks”, to the extent they exist, are a subset of Representative Peaks and are used to differentiate one crystalline polymorph from another crystalline polymorph (polymorphs being crystalline forms having the same chemical composition). Characteristic peaks are determined by evaluating which representative peaks, if any, are present in one crystalline polymorph of a compound against all other known crystalline polymorphs of that compound to within ±0.2° 2θ. Not all crystalline polymorphs of a compound necessarily have at least one characteristic peak.

Intel XRG-3000 Diffractometer

XRPD patterns were collected using an Inel XRG-3000 diffractometer equipped with a curved position sensitive detector with a 20 range of 120°. Prior to the analysis, a silicon standard (NIST SRM 640c) was analyzed to verify the Si 111 peak position. Samples were prepared for analysis by packing them into thin-walled glass capillaries. Each capillary was mounted onto a goniometer head and rotated during data acquisition.

PANalytical X'Pert Pro Diffractometer

The specimen was analyzed using Cu radiation produced using an Optix long fine-focus source. An elliptically graded multilayer mirror was used to focus the Cu Kα X-rays of the source through the specimen and onto the detector. The specimen was sandwiched between 3-micron thick films, analyzed in transmission geometry, and rotated to optimize orientation statistics. A beam-stop was used to minimize the background generated by air scattering. Soller slits were used for the incident and diffracted beams to minimize axial divergence. Diffraction patterns were collected using a scanning position-sensitive detector (X'Celerator) located 240 mm from the specimen. Prior to the analysis a silicon specimen (NIST SRM 640c) was analyzed to verify the position of the silicon 111 peak.

Light Microscopy

Light microscopy was performed using a Leica DM LP microscope equipped with Spot Insight color camera (model 3.2.0). A 10×, 20×, or 40× objective was used with cross polarizers and a first order red compensator in place to view samples. Samples were placed on a glass slide, then a cover glass was then placed over each sample. Samples were analyzed as a dry mount and suspended in mineral oil. Images were acquired at ambient temperature using Spot software (v.4.5.9 for Windows). Micron bars were inserted onto the images as a reference for particle size.
